When cutting stainless steel or aluminum, the laser beam simply melts the material. The material then melts, burns, or vaporizes leaving an edge with a high-quality finish. The beam has to be precisely focused so that the shape of the focus spot and the density of the energy in that spot are perfectly round and consistent, and centered in the nozzle. If you've ever seen a laser pointer projecting a spot onto a screen, you'll realise that a laser … One of our team members will be in touch soon. Though the full term is rarely used anymore, the word “LASER” is an acronym for Light Amplification by Stimulated Emission of Radiation. Material Compatibility: Some of the most commonly used materials for our laser systems. Laser cutting is a digital manufacturing technology, working on 2D vector files. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf. The laser cutter is one of the most useful tools in a modern shop. You’ll also see lasers being used in medicine to destroy cancer tumors, cauterize blood restores, and restore eyesight by repairing detached retinas. The cutting head follows programmed instructions to create specific cuts and holes according to design specifications. \"Star Wars,\" \"Star Trek,\" \"Battlestar Galactica\" -- laser technology plays a pivotal role in science fiction movies and books. This focus produces very uniform light that will travel long distances. Laser cutting is a type of thermal separation process. Lasers come in a wide array of types and strengths, producing extremely accurate cuts that facilitate the creation of intricate shapes. The laser burns away or vaporizes the material, leaving the desired shape behind. Most people already know that the word “LASER” is actually an acronym for Light Amplification by Stimulated Emission of Radiation. In the case of a typical CO2 laser, that wavelength is in the Infra-Red part of the light spectrum, so it is invisible to the human eye. The high power density results in rapid heating, melting and partial or complete vaporizing of the material. There are two main types of lasers used in cutting, CO2 lasers and neodymium (Nd) and neodymium yttrium-aluminium-garnet (Nd-YAG). This video explains the process of laser cutting - using a high powered laser to cut, etch and engrave a material. Welding varies in methodology and requirements for each material. It may be bounced in different directions by a number of mirrors, or “beam benders”, before it is finally focused onto the plate. How does it work? Terms and Conditions A laser cutter is a machine that uses a laser to cut and engrave material. The laser beam is a column of very high intensity light, of a single wavelength, or color. Well, actually, one of the mirrors isn't perfectly reflective. When cutting mild steel, the heat of the laser beam is enough to start a typical “oxy-fuel” burning process, and the laser cutting gas will be pure oxygen, just like an oxy-fuel torch. Our standard thickness capabilities range from 16-gauge sheet metal to steel plates 1-1/4 inches thick. By focusing the large beam down to a single pinpoint, the heat density at that spot is extreme. Laser cutting is a type of thermal separation process. Initially, the beam pierces the material with a hole at the edge, and then the beam is continued along from there. The laser beam is a column of very high intensity light, of a single wavelength, or color. Concentrated energy is the core premise of laser cutting. A laser cutting machine works by focussing a beam of laser light onto a piece of material. First, a curved mirror or lens concentrates the light into a single point. Mathis Company, Precision Laser Cut Stainless Steel Plate, Custom Formed Steel Section Component Part, Custom Plasma Cut & Beveled Steel Component Part, Considerations for Welding Stainless Steel, Laser Cutting Stainless Steel vs. This manipulation of the light waves gives a laser its signature brightness and narrow focus. FAQS: The most frequently asked questions about our laser systems. Plasma Cutting. In order to flush resulting emissions and residues such as slag or melt from the kerf, the laser optic is fed compressed air via a jet system. Posted in The mirrors form a resonator that builds up the light energy in the beam. While the quality remains high, so too does the level of power that the fiber laser beam delivers. What is the Best Value – Plasma, Laser or Waterjet, Quality Assurance Information for Suppliers. Cut quality can be affected by raising or lowering the focal point from just above the surface of the plate, at the surface, or just below the surface. And the laser cutting gas will be pure oxygen, just like an oxy-fuel torch. There are various nozzle widths available. Lasers can etch and cut through many different materials. In a C02 laser cutter, light is produced when electricity runs through a gas-filled tube with mirrors at both ends. If the focal point is even slightly too low or too high, it can alter the quality of the cut.

Laser light - a special wave. Laser cutting procedure explained technically. Lasers can cut through mild steel, stainless steels and aluminum with only a small kerf without otherwise damaging the remaining material. Laser cutting machines generate a ¾-inch wide laser beam. In the meantime, continue to browse our Project Portfolio. , Tagged with Slits with a width as narrow as 0.1mm can be achieved using the laser cutting process. Once the laser beam has completely penetrated the material at one point, the actual laser cutting process begins. This is a quick and easy way to replicate the same design on different materials, or create multiple copies of the same object. Applications: Popular industries using the laser systems for all types of engraving and cutting work. The beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine’s beam path. The beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine’s beam path. Laser Cutting Methods. There are many, many other parameters that affect cut quality as well, but when all are controlled properly, laser cutting is a stable, reliable, and very accurate cutting process. Laser, A capacitive height control system maintains a very accurate distance between the end of the nozzle and the plate that is being cut. The dot of the fiber laser beam can be made incredibly small, perfect for applications such as laser cutting. The laser cutter itself is built of a laser resonator which, depending on the cutting method, contains either a gas mixture of a crystal body or glass fibers. Please use the form below to get in touch. When laser cutting mild steel, the heat of the laser beam is enough to start a typical “oxy-fuel” burning process. Custom Sheet Metal Fabrication From G.E. Part 1 On a CNC laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate. As the lasing material is stimulated, the beam is reflected internally by means of a partial mirror, until it achieves sufficient energy to escape as a stream of monochromatic coherent light. Laser cutters work by directing a very powerful laser beam, at a precise focal length, onto a material which they either cut or etch, depending on how the laser … The focused laser beam goes through the bore of a nozzle right before it hits the plate. The time the job takes on a laser is dependent on the type of materials and the thickness of the materials being cut. Laser cutters use a thin, focused laser beam to pierce and cut through materials to cut out patterns and geometries specified by designers. Generation of the laser beam involves stimulating a lasing material by electrical discharges or lamps within a closed container. Each laser beam is a collection of light beams with identical or nearly identical wavelengths. Now think about focusing 6 KWatts of energy into a single spot, and you can imagine how hot that spot will get. Depending on the material to be cut the cutting methods used differ: Fusion Cutting ( high pressure cutting): The material is fused by the energy of the laser … Laser cutting and 3D printing Laser cutting A laser cutter can use a computer aided design (CAD) to cut or engrave complex shapes out of card, wood, foam, plastic or circuit board. The process works by having a focused and precise laser beam run through the material that you are looking to cut, delivering an accurate and smooth finish. involved in this tool that will give your business the capability to transform any object into a prized posession.
